The construction of the pipe line was commenced atboth ends, and considerable difficulty was experiencedin closing the gap at the center of the line. This was due to the alteration in length, resulting from thechange of temperature. Before sunrise the openingwas 7 feet 8 inches, but in the afternoon this gap wouldclose to 7 feet, the change being due, of course, to ex-pansion under the heat of the suns rays. This diffi-culty was met by fitting a length of 20 inch lap-welded pipe to the adjoining ends of the pipe line before joint wasleaded andcalked, and thepipe filled withwater beforethe heat couldproduce anyexpansion.
